Line 65 in my case change:
define('PRODUCT_NAME', 'Feng Office');
to
define('PRODUCT_NAME', 'whatever-you-want');
the only thing I don't like about this approach is now it says "Shai Inc. - Collaborate" which is fine. But the footer says "Powered by Collaborate 1.7-beta2". I want to give credit to Feng Office and would rather it says the original "Powered by Feng Office 1.7-beta2"
Is there a better way to do this?
There is this option, but it doesn't seem the cleanest way to do it:
